Random bug with LatLon query #15

Usually it works well, but sometimes it seems that "parseWeatherInfo" returns a null value.

This is the stack trace:

Thank you for your feedback. Exactly, using a null value returned from "parseWeatherInfo" causes this problem. I have fix it by arranging the parse process, and it can correctly handle a NPE now.
